If you use the Max interface, then the panning shortcut is the same as in Max.
If you want to change it, go to menu, preferences, 3rd tab gives a list of shortcuts, navigate to the Pan shorcut, and then change it back holding the right mouse, by deleting the existing shortcut, and doing the operation you want to the shortcut to be ( meaning, you just hold down the RMB, don't try to write anything, just do the action)
